This invention relates to weather strips for swinging double doors, and its principal objeet is to prevent rain, snow or wind from entering a building through the between the meeting edges of swinging double doors. Usually one of the pair of such doors is pro vided with an astragal moulding strip, and in case both of the doors are free to be opened, this strip often interferes with the closing of oneof the doors, because the door containing the strip may close first and, consequently, the other door will swing against the strip and will remain partly open. Doorsof public buildings, such as schools and the like, are usually providedwith door checks for automatically closing the doors, and unless care is taken in allowing the doors to close in their proper order, one is likely to be held partly open by the astragal strip.

In accordance Withthe present invention, I provide a pair of overlapping contacting rubber or other resilient strips along the two meeting edge portions of swinging double doors, which strips effectively prevent the entrance of rain, snow or wind through the gap between the doors and yet allow either door to be opened first or closed first. The

invention consists, therefore, in weather strips for swinging double doors having overlapping contactlng resilient portions secured to the meeting edge portions of swinging double doors.

It further consists in the several novel features hereinafter fully set forth and claimed.

The invention is clearly illustrated in the drawing accompanying this specification in which Figure 1 is a side elevation of a pair of swinging double doors with simple embodiment of the present invention applied thereto;

Fig. 2 is a horizontal section taken on the line 22 of Fig. 1;

Fig. 3 is a plan of the meeting edge por tions of two doors with the weather strips applied thereto and showing the same upon an enlarged scale; and

Fig. 4 is a perspective view of a fragment of one of the strips.

Referring to said drawing, the reference character 5 designates a door frame upon which a pair of swinging double doors 6 and '2' are carried by hinges 8. As usual, the doors swing outward in the direction of t ie arrows a in Fig. 2. Ordinarily, door checks (not shown) are employed for closing the doors.

Secured to the meeting edge portions of the doors are rubber or other resilient fiatstrips 9, which extend the full length of the doors and slightly beyondthem. The rubber strips 9 are held in U-shaped metal binding members 10 through which nails or screws 11 are driven into the doors to secure the rubber strips thereto. Each binding member is doubled over at one ed e, being preferably bent inwardly and forming the doubled edge portion 12, said doubled edge portion being positioned at the outer side of the flexible strip 9 on the door, so as to securely clamp and retain said strip in position and also to form a rounded bead 13 on the outer edge part, 111 order that said strip will bend and be deflected smoothly on said bead, and the double doors are enabled to swing freelv during the opening and closing thereof.

The free edge portions of the rubber strips project beyond the adjacent edges of the doors, and when the doors are closed, said. strips overlap each other, the one deflecting the other slightly out of its normal plane. When the strips are in the, position seen in full lines in Fig. 3 and the door 7 is opened first, the rubber strip 9, carried thereby, moves away from the rubber strip 9 on the door 6, but in case the door 6 is opened first, the rubber strips are bent, as shown in dotted lines in Fig. 3, until the rubber strip on the door 6 passes the one on the door 7, after which the rubber strips assume their normal flat condition.

If the door 6 is later closed after the door 7 has been closed, the rubber strip on the door 6 will simply deflect the protruding ed e portion on the door 7 slightly, although itmakes a close contact therewith throughout its enand when nailed or screwed to the door holds the rubber strip imposition with the protruding edge portion in contact with the protruding edge portion oftheother'rubber strip.

' Itwill be evident from the above that the gap between the meeting edges of swinging V i I double'doors may be effectively closed by the application to such doorsof a. pair of weather strips embodyingthe present invention, and theteach door isfree to close fully after the other one has been closed,thereby protecting the interior of'the building against the entrance of rain, snow and wind through the gap between swinging double doors.
